introduction the knowledge about spatial variability of precipitation is a key issue for regionalization in hydro-climatic studies. measurements of meteorological parameters by the traditional methods require a dense rain gauge network. but, due to the topography and cost problems, it is not possible to create such a network in practice. in these cases the spatial distribution pattern of precip...

Precipitation is the only water supply and most important factor affecting vegetation growth on the slopes of semi-arid Loess Plateau of China. Based on precipitation data from 7 synoptic stations in the study area over the period 1957-2012, the trends of precipitation and standardized precipitation index (SPI) were analyzed by using linear regression, Mann-Kendall, and Spearman's Rho tests at ...

the aim of this study is to assess some synoptic characteristics of heavy precipitations in southwestern parts of iran and evaluate the relationship between them with the madden-julian oscillation (mjo). research is conducted with regard to distribution of precipitation per month and identifying their steam sources. daily records of the november-april precipitation data in abadan, ahwaz, bandar...

The variation of precipitation plays an important role in the eco-hydrological processes and water resources regimes on the Tibetan Plateau (TP). Based on the monthly mean precipitation data of 65 meteorological stations over the TP and surrounding areas from 1961 to 2015, variations, trends and temporal–spatial distribution of precipitation have been studied; furthermore, the possible reasons ...

An analysis of the relationship between changes in Arctic stratospheric ozone (ASO) and precipitation eastern North America (38°–54°N, 65°–87°W; PENA) was performed using observational reanalysis data coupled with Whole Atmosphere Community Climate Model version 4 (WACCM4). We found that March ASO exhibits a strong correlation PENA April, indicating one-month leading exerts potentially impact o...

[1] We perform two 23 year simulations using a regional climate model coupled with the National Center for Atmospheric Research Community Land Model version 3.5 (RegCM‐CLM) to investigate land‐atmosphere coupling in the continental United States during the cold season (October–April) and the role of soil water phase. One simulation allows the land surface to interact freely (RunI) while the oth...

This study evaluates the precipitation product of the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG) over the Mexican region during the period between April 2014 and October 2015 using three different time scales for cumulative precipitation (hourly, daily and seasonal). Also, the IMERG data have been analyzed as a function of elevation given the rain gauges ...
